Unable to cast exception in Distributed Transaction

[djryan]

I'm doing a distributed Transaction using Oracle and Sql Server. Everything succeeds including commiting the results to Oracle and SQL Server but I recieve the following exception in the Debugger.

{"Unable to cast object of type 'Devart.Data.Oracle.ak' to type 'Devart.Data.Oracle.a3'."}

System.InvalidCastException was unhandled

We could not reproduce the issue. Could you please specify the version and edition of dotConnect for Oracle.

This appears to only happen if I choose direct connection. It is working now if I use an Oracle home.

[Pinturiccio]

We could not reproduce this issue with direct mode either. Could you please specify the version and edition of dotConnect for Oracle, and, if possible, send us a test project with DDL/DML scripts?
